I have a vib in the front under the driverside, It only occurs when taking off and more when turning. The rear vibs from 45-60 mph. I am thinking of having a 1/2" cutoff my shackles and installing degree shims. What size shim should I get? Also I want to replace the ujoints in the drive shaft. Should I get sealed or greasable?

Sounds like the drivers side axle joint is bad. Turn wheels all the way to the right. Reach in and see if you can wiggle the joint back and forth. Does it clank. Not good. Replace the shaft. Don't bother replacing the joint. too much work and can be more expensive if you take it somewhere.

Sounds like a u-joint to me. Check them all. Replace the ones you need to. Save the joints for spares if you aren't already in the habit of carrying new ones for spares.

It could also be a bearing problem I suppose. But I'd start with the joints. Check the bearings on the front by jacking up the tire and shake it side to side. A very small amount of movement is ok. There will be no doubt if it's bad.
